摘要：
A low-frequency sound generator for generating intense sound.
It comprises a resonator (10). Pressurized gas is supplied to the resonator as pulses through a feeder (13). The sound generator comprises means for positive feedback of the sound pressure in the resonator to the feeder at a predetermined resonance frequency of the resonator but not at other frequencies.
